Frequently Asked Questions about Changing Watch Crystals
Here are answers to some common FAQs about changing watch crystals:
What is the best material for a replacement crystal?
Sapphire is the most durable and scratch-resistant option. Mineral and acrylic crystals are less expensive but easier to damage.
Can I polish a scratched crystal instead?
Light scratches can be polished out but deeper abrasions require replacement. Sapphire crystals are difficult to polish.
How do I know which gaskets to replace?
As a rule, always install new casebacks and crystal gaskets when opening up a watch. Reuse leads to leaks.
What is the best adhesive for attaching the new crystal?
Pressure-sensitive putty-like Rodico allows temporary adhesion without oils damaging the gasket.
Do I need special tools for this?
You’ll need a crystal press, case wrench, movement holder, tweezers, and loupe at minimum. Kits are available.
How long should this repair take?
Expect to spend 1-2 hours your first time. Experienced watchmakers can do it in 30 minutes.
Can I damage my watch attempting this?
There is a small risk of harm if you use improper tools and force. Take it slow and use plastic tools only.
Is there an alternative way to install the crystal?
Some professionals use hot oil to melt the gasket and then set the crystal. Not recommended for beginners.
How do I clean the empty case before the new crystal?
Use a dust blower followed by wiping carefully with a new lint-free cloth. Don’t leave any fibers or oils.
Why is water resistance testing important?
If the new seal isn’t tested and fails, moisture can enter and corrode the movement leading to costly repairs.
Can you replace the crystal on a watch?
Yes, it is possible to replace the crystal on most watches. Watch crystals protect the dial and can become scratched or damaged over time through normal wear and tear.
Replacing a watch crystal is an easy and affordable way to make a watch look brand new again. It can be done through a quick and simple process by a knowledgeable watch repair professional. They simply pop off the old crystal and fit a replacement crystal into the gasket.
Suitable replacement crystals can be sourced aftermarket for most common watch brands. Acrylic crystals can be cut and polished, while sapphire crystals offer increased scratch resistance. The cost is usually only $25-$100 depending on the watch and crystal type.
So if the crystal on your favorite timepiece has become scratched up and worn, don’t fret! Having it expertly switched out with a fresh replacement can restore the aesthetic and wearability of a beloved watch rather than having to replace the entire watch itself.
How much does it cost to replace crystal on watch?
The cost to replace a scratched watch crystal typically ranges between $25 to $100, depending on the watch and the type of replacement crystal chosen.
Acrylic crystals on basic quartz watches can be swapped for as little as $25 from a reputable watch repair shop. However, for higher-end mechanical watches like Rolexes, sapphire crystal replacements cost $70 to $100 – especially if the installation has added complexities around waterproof gaskets.
If watch owners only have surface-level scratches, watch repairers can also expertly polish existing acrylic crystals back to flawless condition for around $20-30. However sapphire remains unfixable if scratched.
In summary – customers can get quality watch crystal replacements for most mid-range to luxury watches for less than $100. Considering a new watch often costs in the thousands, repairing a damaged crystal is an inexpensive way to revive your timepiece back to near-mint condition.
Can the glass of a watch be replaced?
Yes, it is possible to replace the glass (or crystal) on most watch models. Watch crystals protect the watch face from damage but can crack or scratch with regular wear over time.
Luckily, replacing a watch’s glass or crystal is a straightforward fix performed by professional watch repair services. They open the watch case, remove the broken crystal, and install a suitable replacement crystal to match the watch.
Materials like acrylic, sapphire, and mineral glass can be sourced as direct replacement glass options for most watches. The cost for a total crystal replacement is typically between $50-100 depending on the complexity.
In some cases for high-end watches, original manufacturer parts may be needed. But watch glass replacement remains one of the most common and cost-effective watch repairs – restoring beauty and function versus replacing the entire watch. So with some expert help, damaged watch glass can almost always be swapped out as well as new.
How do you remove crystals from a watch?
While removing a watch crystal is possible to do at home, it requires great care and specialty tools to avoid damaging watch components or compromising water resistance.
The safest method is to use a crystal lift, a suction cup tool specifically for lifting watch crystals safely. The crystal lift gently adheres to the crystal, enabling the watchmaker to slowly and uniformly lift the crystal out of its securing gasket.
Another common technique relies on a crystal press. The watch is positioned dial down on the lower die of the press. With gentle and even pressure applied to the crystal’s edges via the top die, the crystal releases from the gasket seal and can be lifted.
In both instances, replacing any dislodged gaskets and waterproofing rings is critical before resetting the new crystal, as opening the watch compromises integrity. So for inexperienced owners, consulting a professional watch repairer avoids any rookie mistakes or damage when changing crystals.
Is watch crystal glass or plastic?
Watch crystals can be made from plastic, glass, or synthetic sapphire – depending on the make and model.
Traditionally, inexpensive watch crystals were made of acrylic plastic due to its ability to resist shattering. Mid-range watches often use hardened ‘mineral’ glass for increased scratch resistance. Meanwhile, high-end watches tend to utilize near-impervious synthetic sapphire crystals.
While glass watch crystals provide the most durable protection, they can still shatter under significant impacts. Plastic acrylic crystals instead flex on compression to resist cracking. But they scratch more easily over time.
So modern watches feature a range of plastic, glass, or sapphire crystals to balance durability, weight, and cost needs. But rest assured – no matter its material – a quality watch’s crystal can be replaced if damaged, extending the timepiece’s usable lifespan through care and upkeep.
What glass does Rolex use?
Rolex uses synthetic sapphire crystal glass exclusively to cover the watch face for all their modern watches.
Sapphire crystal is next to diamond in hardness, making it incredibly scratch-resistant and almost impossible to break under normal wear. This durability and optical clarity are why it is valued over traditional silicate glass.
A signature feature of Rolex watches, the near-impervious sapphire crystals protect the precious Rolex movements for decades and take hard abuse without showing signs of wear. This reliability matches Rolex’s brand image for unmatched robustness and longevity.
The sapphire glass fronts are created synthetically by Rolex specifically for their watches. Combined with tight quality seals that enhance water resistance, they demonstrate Rolex’s continual technical innovation and mastery of watchmaking craft. Owners can thus enjoy the sapphire glass for both beauty and protection throughout their Rolex’s remarkable lifetime.
Can a watch crystal be polished?
Yes, a watch crystal can be polished. Professional watchmakers have the expertise to carefully remove scratches and imperfections from watch crystals, restoring them to their original clarity and shine. This process can enhance the appearance of the watch and prolong its lifespan, making it a popular option for those looking to refresh their timepiece without replacing the crystal entirely.
